HAN D- STAMP.

SPECIFICATION forming part of Letters Patent No. 230,848, dated August3, 1880. I Application filed Mayifi, 1880. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES 0. WILSON, of Washington, in the county ofWashington and District of Columbia, have invented a new 5 and valuableImprovement in Hand-Stamps; and I do hereby declare that the followingis a full, clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure] of the drawings is a representation of a vertical section of myimproved handstamp. Fig. 2 is an end view of the same, and Figs. 3, 4,5, and 6 are details.

This invention has relation to improvements in oscillating hand-stampsof the self-inking class.

The object; of the invention is to simplify and improve the mechanismwhereby the fixedmatter plate is oscillated, so as to decrease friction;and, secomlly, to provide means for automatically taking up the slack ofthe dating-bands and for changing the dates by turn- 5 ing the handsahout their hearings.

The nature of the invention to these ends will be fully shownhereinafter.

1n the annexed drawings, the letter A designates a horizontal metallicplate, usually recessed on its. under side for the reception of theink-pad B, and supported upon the end legs, The end'leg U is verticallyslotted, as shown at a, the slot being plain and rectangular. The otherleg is also vertically slotted. at b, the slot being somewhat widerthant'hat of leg 0, and being provided in one edge, at about the middleof its length, with a curved recess, a, and a centrally-projecting stud,c, of rounded form, extending out into the slot from the side of thisrecess a short distance beyond the slot-wall.

The legs 0 C are formed of metal, and may be struck out with a diecomplete and ready for use, or they may be cast.

5 D indicates the fixed-matter plate, having raised characters on itsface around a slot, (1,

cut therein, and provided at one end with the journal 0, cxtoudingthrough the slot 0 of log 0, and at the other with a journal, 0, extend-50 .in-g through the slot I) of leg 0, and both journaled in the legs dof an invertedU-shaped bail, D, passing over the pad-plate and carry ingthe hollow handle D. The plate A carries a central projecting stem, D,extending into the handle and hearing at its end against a spiralspring, S, in the hollow of the said handle.

E indicates a tumbler formed of metal, and of the same width as the slotb. This tumbler is fixed to the journal 0, or to the adjacent end of thefixed-matter plate, this alternative being preferred, and it movesfreely up and down in slot 11. [t is provided with aroundedet'lge notch,i, of a size to receive thecorrespondingly-rounded stud c, and itsopposite edge is curved, as shown at i, the radius of the are being thedistance from the extremity of the stud to the opposite sidewall of slot1). At each side of the notch i' of the tumbler E is a prong, 1'. Whenthe handlcis pressed down in the act of stamping the tumbler moves in aright line until the prong i on one side comes. in contact with the studc". It thcn'cnters the recess at the upper side of the said stud, andthe tumbler is turncthtihe notch i receiving the stud c at right anglesto its form r position. the other prong being in the' reces at the lowerside of said stud. ltthen turns over end for end;.'5and presents theinked face of the fixed-matter plate to the article to be stamped. Thereverse movement of the said plate is caused by the reaction of springS, and the plate is turned side for side, with its pi-intingfacc againstthe path-by an cxaetl reversed operation of the tumbler and its con- 85.

nections on leg 0'.

F indicates a preferably tapered quadrangular bearing extending throughthe slot (1 of the fixed-matter plate, and having ,one face nearly on alevel with ,the faces of the charac- 9o ters on said plate. The bearingF has end offsets, f, and is secured to the back of the plate bysuitable screws or other t'asteniugs passing. intothe same through ;saidoffsets. Project ing into the opposite face of hearing F, near 5 itsends, and working in perforations therein endwise, are two parallelmetallic rods, G, of

suitable length and rigidity, that pass into gnide-perthrations in theadjacent face of the bearing H, and are rigidly secured thereto. Thishearing is rounded or semi-cylindrical at its hearing-face and tapers 0dat its sides adjacent to bearing F, to avoid interfering with theendless dating-bands I passing around said bearings F and H, and holdingthem together; or it may have tapering end ott'sets, g, for theattachment of the euds'ot' the guide-rods G.

The dating-bands I are held properly tense by means of the spiralsprings S, arrangedon rods G between the bearings F and H, the saidsprings also taking up the slack thereof as it occurs from useautomatically.

As shown in Fig. 1, the bearing H may be transversely slotted, as at h,the slots being so arranged as to be under the middle line of each ofthe dating-bands. Through these slots spurs j extend out from theperiphery of the wheels J, arranged to rotate independently on an axialshaft, K, extending through the cylindrical bearing H. These prongsengage properly-spaced perforations l in the bands, and extend somewhatthrough them, being designed to facilitate the changing of the dates andmovingthe bands; or the slots and spurred wheels may be dispensed withand simple metallic rings a, lying edge to edge on the hearing H, may beused, one of said rings being under each dating-band.

When used in this manner the rings will be prevented from lateraldisplacement by the end flanges, n, which are also used when the bearingaforesaid is not provided with devices for operating the bands.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a hand-stamp, the combination, with the stainplegs (J 0, havingthe vertical slots a b, respectively, the latter being provided with therounded recess 0 in one edge and the horizontally-projecting stud 0extending in the plane of the leg into said slot 1), of the fixed-matterplate D, having the spindles e 0 extending through said slots, and thetumbler E, having the rounded-edge notch and the curved edge i, attachedto the fixed-matter plate, and moving in the slot 2'), substantially asspecified.

2. The combination, with the legs having slots (L b, the latter slothaving the rounded projecting spur e and recesses above and below it, ofthe fixedanatter plate .D, having spindles c 0 extending through saidslot, the round-edged and notched tumbler E, working in slot b andattached to the said plate, and mechanism for depressing and raisingsaid plate, substantially as specified.

3. The combination, with the vertically-reciprocating fixedanatter,plate D, having the round-edged and notched tumblerand end spindles, ce, of the legs (3 and C, the latter havingthc spurred slot (1", andmechanism for depressing and raising said plate, substantially asspecified.

4. The combination, with the slotted fixedniatter plate 1), of thequadrangular bearing F, extending through said plate and securedthereto, the guide-rods G, the bearing H, the dating-bands I, passingaround said bearings LI and F, and the spiral tension-springs S, be-

tween the same on rods G, substantially as specified.

5. The combination of the bearing F, rods G, bearing H, springs S, anddatingbands passing around said bearings, substantially as specified.

6. The changeable-matter attachment for handstamps, eonsistin g of thebearing F, having means of attachment to the fixed-matter plate, theguide-rods G, the bearing H, the endless dating-bands I, and the springsS between said bearings, substantially as specified.

In testimony that I claim the above I have hereuntoi'suhscribcd my namein the presence of two witnesses.

U. 0. WILSON.
